Industrial, municipal, sanitary, marine, and infectious waste materials are thermally and chemically converted principally to steam, fuels and environmentally acceptable solids by dehydration, pyrolysis of the solid residue therefrom, and finally gasification of the pyrolysis char residue. In contrast to incineration processes, the products have significant market value and present no atmospheric pollution problems. Temperatures employed range up to about 3000.degree. F.
